Digital Isolators: ADUM1402WSRWZ33-RL Application Field and Working Principle

Digital isolators are suitable for many applications and are commonly used in medical electronics, control systems, communications, automotive, and industrial automation. The ADUM1402WSRWZ33-RL is a digital isolator designed specifically for these applications. This article will discuss the application field and working principle of this isolator in detail.

The application field of ADUM1402WSRWZ33-RL isolator

The ADUM1402WSRWZ33-RL is a two-channel digital isolator that provides isolation between two systems. It is suitable for applications where insulation is required to protect against electrical shocks, surges, or noise. It is also ideal for systems that require enhanced signal integrity.It is suitable for use in medical electronics, control systems, communications, automotive, and industrial automation. In medical electronics, it provides isolation between patient-contained circuits and external systems that control the circuitry. It can also be used in communications systems for providing signal isolation. In automotive and industrial automation, it provides safety from shocks and surges.The ADUM1402WSRWZ33-RL isolator is also ideal for applications where interference from external sources must be prevented. It is designed to provide high reliability by preventing signals between two systems from being transmitted in both directions.

The working principle of ADUM1402WSRWZ33-RL isolator

The ADUM1402WSRWZ33-RL isolator is based on a silicon chip-based isolator which uses opto-isolators to provide electrical isolation between two systems. The opto-isolator is based on three components: an LED, a light detector, and a transistor.The LED emits light which is then detected by the light detector. The light detector then triggers the transistor, which in turn switches on or off the power supply of the two systems. When the two systems are isolated the transistor will be off.The main advantage of using an opto-isolator is that it is able to provide a high degree of electrical isolation while still providing reliable data communication. Additionally, opto-isolation provides protection from any external interference since the LED and detector are sealed in an air gap.The ADUM1402WSRWZ33-RL can also be used as a bidirectional isolator, meaning that it can be used to allow data transmission between two systems in both directions. This is achieved through the use of an array of MOSFETs. The MOSFETs switch on and off when the signal is sent to each channel, thus providing isolation in either direction.

Conclusion

The ADUM1402WSRWZ33-RL isolator is a high-performance digital isolator suitable for a variety of applications, including medical electronics, control systems, communications, automotive, and industrial automation. It is based on a silicon chip and opto-isolation technology which provides electrical isolation while still allowing reliable data communication. Additionally, it can be used as a bidirectional isolator, providing data transmission in both directions.
